154 KING: KADAPAH AND KARNÜL FORMATIONS. [PART Tit. 
There are about 6 feet of flaggy and shaly quartzites (ferruginous) lying over about 10 
feet of the lowest beds, and these are again overlaid by thick-bedded grits. 
Section No. 1, Plate VI, applies to thus much of these beds. 
Again, in the neighbourhood of Googood, the lowest of the Goolcheroos have thin- 
Gooleheroos still thinning Fed out somewhat, there being only about 4 feet of coarse 
onb quartzite grits and conglomerates with thick layers of jaspers. 
Above these comes a series of ferruginous, sandy and micaceous flags—the same as those 
in the gorge at the back of Peddakotla hill, —and again above these are more 
quartzite grits and conglomerates which dip down to the Nuddumdody valley, where 
they become covered up by calcareous shales and limestones (Vaimpully beds). Some 
of the ferruginous sandy flags are slightly ripple-marked and well laminated. The 
intermediate set of flags is about 20 feet in thickness, for a good distance along this part 
of the scarp. 
About four miles further north this hitherto distinctive scarp ceases, there being 
nothing but a very thin deposit of quartzite grits and 
Distinctive scarp ceases. $ eid s : 
conglomerates left lying on the granitoid gneiss. 
So far it has not been necessary to notice the fault-rock which is 
so conspicuous in the country below the scarp, as 
Ridges of ‘ Fault- ۱ ; : 
rock’ in the cmvsran- ‘great ridges and walls of white rock for long dis- 
ES tances; but as the lowest beds of the Gooleheroos 
are in this region often conglomerates of fragments of this fault-rock, it 
may be as well to tréat of it here. 
Opposite Kasaupully, a couple of miles south of Nuddumdody, there is a con- 
spicuous and rugged ridge lying close alongside the boundary of kapAPams. This 
ridge belongs to and runs in the CRYSTALLINES in a north and south direction, with its 
wall-like back dipping about 70? west. It is made up of yellow and reddish jaspery 
quartz-rock (not quartzites) much stringed with white quartz in an irregular manner. 
There is also a good deal of brecciation displayed in nearly all the runs of this fault-rock. 
The interesting feature however, is, that, alongside this ridge the lowest of the quartzites 
are very coarse, dark, brownish-purple grits most thickly crowded with large angular 
Very coarse conglomerates  agments Ob LO all appearance, the very rock constituting 
wd the wall of the ridge. 
In the neighbourhood of Coravypully, about four miles south of the Penn-air, the 
scarp is of thick-bedded grey grits, with just the faintest trace of breccia conglomerate 
of jasper, &c., at the bottom. Here there is a scarp of 13 to 20 feet. 
North of the Penn-air, above Reddypully, there are reddish and purplish sandstones 
and sandy flags lying on coarse granitoid gneiss.
